Objectives. To assess the pooled effects of shift work on poor mental health and evaluate whether these differ in men and women.
Method: PubMed, Scopus and Web of Science databases were searched for either longitudinal or case-control studies of shift work exposure associated with adverse mental health outcomes. These outcomes were grouped as: anxiety symptoms, depressive symptoms or general poor mental health symptoms. We calculate pooled effect sizes (ES) using random-effect models, and meta-regression analysis to explore sources of heterogeneity.
Results: Seven articles were included, with 28,431 unique participants. Compared with day workers, shift workers had a higher risk of any adverse mental health outcomes (ES: 1.28; 95%CI: 1.02-1.62, I2:70.6%), specifically for depressive symptoms (ES: 1.33; 95%CI: 1.02-1.74, I2: 31.5%).Gender and overall risk of bias explained 90% and 0.61% of the heterogeneity of results, respectively. Sensitivity analysis showed that the pooled effect size for adverse mental health outcome was higher in female shift workers than female day workers (ES 1.73, 95%CI 1.09-2.76).
Conclusions: Shift workers, in particular women, are at increased risk of depressive symptoms and adverse mental health outcomes. Workplace health promotion programs and policies are needed to minimise shift workers’ risk of poor mental health.
